[Book Review] Failure Is Not An Option by Gene Kranz

Failure Is Not An Option describes the Mission Control career of Gene Kranz, the archetypal spacecraft flight director. The book covers the period from Mercury to Apollo with additional chapters of Gene Kranz’s early life and USAF pilot experience.

This book is a gem in that Kranz tells the story of the people, the machines, and the infrastructure. He clears shows the challenges, the solutions, the trials, the magnificent success of the Apollo program, and how NASA moved on.

I particularly enjoyed the discussions of infrastructure development (e.g. flight computers, tracking networks). Several of his insights were introduced into my own R&D group, as we see similar challenges. This book would be useful for startup managers and those people developing the infrastructure needed for a complex engineering or science program.

Strongly recommended for aerospace engineers and program managers.

“The Kranz Dictum” after Apollo 1

Spaceflight will never tolerate carelessness, incapacity, and neglect. Somewhere, somehow, we screwed up. It could have been in design, build, or test. Whatever it was, we should have caught it. We were too gung ho about the schedule and we locked out all of the problems we saw each day in our work. Every element of the program was in trouble and so were we. The simulators were not working, Mission Control was behind in virtually every area, and the flight and test procedures changed daily. Nothing we did had any shelf life. Not one of us stood up and said, “Dammit, stop!” I don’t know what Thompson’s committee will find as the cause, but I know what I find. We are the cause! We were not ready! We did not do our job. We were rolling the dice, hoping that things would come together by launch day, when in our hearts we knew it would take a miracle. We were pushing the schedule and betting that the Cape would slip before we did.

From this day forward, Flight Control will be known by two words: “Tough” and “Competent”. Tough means we are forever accountable for what we do or what we fail to do. We will never again compromise our responsibilities. Every time we walk into Mission Control we will know what we stand for. Competent means we will never take anything for granted. We will never be found short in our knowledge and in our skills. Mission Control will be perfect. When you leave this meeting today you will go to your office and the first thing you will do there is to write “Tough and Competent” on your blackboards. It will never be erased. Each day when you enter the room these words will remind you of the price paid by Grissom, White, and Chaffee. These words are the price of admission to the ranks of Mission Control.

[Book Review] Roskam’s Airplane War Stories

Dr. Jan Roskam’s Airplane War Stories is a seriously good book. The lessons come in bite sized tales (“War Story #”) with the wonderful treat of providing the moral (“Lesson”) in his own words.

This book won’t teach you how to analyze aircraft -Dr. Roskam’s other books take that charge- but once you do know the mathematics, the concept, and the application, this book is a lot of fun to read.

The first part of the book is a bit better than the later part. It is slightly disappointing that the book does not cover as many aircraft design topics with specific discussions of the aircraft features.

Thank you Dr. Roskam for this and other books. The book is available through several sources:
